2018 JBL speaker upgrade?

So I have the JBL sound system in my car and as some of you may know, its Garbage.
Im upgrading the head unit to the Pioneer 7201 NEX
and am looking to upgrade all the speakers as well,
does anyone have any reconditions?
I saw a threat of a complete "upgrade for 250$"
and but I know the JBL is wired a little bit differently and so I am interested if anyone has any knowledge on good ideas of a not incredibly expensive upgrade to these trash JBLs?
any help is appreciated, thank you!

 

Really depends on your budget. To stay cheap, replace all speakers with 2ohm aftermarket speakers.
To throw some money at it. Take out the jbl amp, replace with good amp, and replace all speakers with more common 4ohm speakers

 

Well, when you decide to trash your JBL stuff. Give it to me, I'll take'm.
